Cloud computing offers a prominent service for data storage known as cloud storage. The flow and storage of data on the cloud environment in plain text format may be main security threat. So, it is the responsibility of cloud service providers to ensure privacy and security of data on storage as well as network level. The following three parameters confidentiality, integrity and availability de...

Despite of their rising popularity, current cloud storage services and cloud-backed storage systems still have some limitations related to reliability, durability assurances and inefficient file sharing. We present SCFS, a cloud-backed file system that addresses these issues and provides strong consistency and near-POSIX semantics on top of eventually-consistent cloud storage services. SCFS pro...

loud computing has become an important thing in computer field. Cloud computing takes information processing as a service, such as storage and computing. Data integrity is important thing in cloud storage. In certain situations, clients should store their data such as image or text in multi cloud. When the client stores his/her data on multi-cloud servers, the distributed storage and integrity ...

Cloud computing is a most alluring technology that facilitates conducive, on-demand network access based on the requirement of users with nominal effort on management and interaction among cloud providers. The cloud storage serves as a dependable platform for long term storage needs which enables the users to move the data to the cloud in a rapid and secure manner. It assists activities and gov...

Abstract— High-performance computing and vast storage are two key factors required for executing data-intensive applications. In comparison with traditional distributed systems like data grid, cloud computing provides these factors in a more affordable, scalable and elastic platform. Furthermore, accessing data files is critical for performing such applications. Sometimes accessing data becomes...

—Cloud computing allows the users to access the shared pool of configurable resources such as compute, network and storage on-demand basis from the cloud Data Centers. Cloud storage provides the storage resources to the cloud users over the network. The massive growth of cloud data due to the applications such as video streaming, big data processing, social networking, banking and scientific a...

Cloud computing has been popular as the IT architecture. Cloud service providers offer many services based on cloud computing. Cloud storage service is the cloud services which can provide a huge storage space to solve the bottleneck of the storage space of local end users. However, cloud storage service may have data security because the users’ data is not stored in their own storage. In this ...

The goal of VISION Cloud, a European Commission funded project, is to design a new scalable and flexible storage cloud architecture able to provide data-intensive storage cloud services. The proposed environment employs a distributed file system on top of a set of storage rich nodes composing a cluster. Several clusters constitute a data center, while multiple geographically distributed data ce...

Despite the many advantages provided by cloud-based storage services, there are still major concerns such as security, reliability and confidentiality of data stored in the cloud. In this paper, we propose a reliable and secure cloud storage schema using multiple service providers. Different from existing approaches to achieving data reliability using redundancy at the server side, we propose a...

In recent years Cloud computing has become the infrastructure which small and medium-sized businesses are increasingly adopting for their IT and computational needs. It provides a platform for high performance and throughput oriented computing, and massive data storage. Subsequently, novel tools and technologies are needed to handle this new infrastructure. One of the biggest challenges in this...
